A:Though largely defined by the quality and size of the photos in question, an 8GB memory card is capable of holding up to 1,000 24-megapixel photos. Fewer pixels require less data, and thus more can be stored on a memory card.

A:RAM, short for random access memory, is used by computers to store data that is being used currently or was recently used. Accessing data stored in RAM is much quicker than directly accessing data stored on the hard drive, allowing a computer to run much faster.

A:The number of pictures that a 4GB memory card holds is directly related to the size of the pictures, but it generally has the capacity to store 1,140 photos that are 10 megapixels. This figure is based on the fact that 1 megapixel equals about 1,000,000 pixels, that 1MB is equal to about 1,000,000 bytes and 1GB equals about 1,000MB.

A:CDs and DVDs that have already been burned with music and other data can still accommodate more files, but only if they are configured as multi-session discs. Burning additional music to a multi-session disc requires that the disc has remaining free space.

A:The best way to destroy a hard drive is to magnetically degauss it first. If a hard drive is passed through a very strong magnetic field, the data on it will be permanently destroyed. The platters that spin the drive should then be physically destroyed.

A:The first 8-inch floppy disks created in the 1970s had a capacity of 80 kilobytes. By 1986, IBM improved its design, resulting in the 3.5-inch floppy disk, which had a maximum capacity of 1.44 megabytes.

A:With a PC, if a hard drive failure is imminent, the user typically needs to replace it after creating a set of recovery discs and backing up personal files to another hard drive or USB storage device. After installing the new drive and performing system recovery, the OS should be loaded. Personal files can be uploaded to the new hard drive after recovery.

A:An industry standard 74-minute audio compact disk can hold 650 megabytes of data. Other industry standards are the 80-minute, 700 megabyte disks and the 21-minute, 185 megabyte disks. CDs with higher capacity, up to 890 megabytes, exist but don't conform to industry standards and may not work in all readers.

A:A hypermedia database is a computer information retrieval system that allows a user to access and work on audio-visual recordings, text, graphics and photographs of a stored subject. The World Wide Web is a perfect example of a hypermedia database.

A:Flash memory cards consist of large numbers of individual cells, each of which contains a set of transistors. Under normal circumstances, current flows between the transistors and into a drain. When a charge is applied to one of the transistors, the current flow gets blocked. The amount of current passing through the cell effectively flips it from a one to zero, allowing for the storage of binary data.

A:A hard disk's actuator is the electronic device that moves the actuator arm across the hard disk's platter, and it works hand in hand with other components to locate, write, read or delete information. The actuator assembly operates similarly to how a record player plays a vinyl record.

A:When a cell phone says that the "SIM card is full," this most likely this means that the SIM card has reached its maximum storage capacity. A user needs to delete contacts and text messages or upgrade to a larger SIM card for more storage space.

A:A gigabyte is much larger than a megabyte. According to the National Institute of Standards and Technology, there are 1000 megabytes in a gigabyte. However, in some cases, a gigabyte is defined as 1024 megabytes.

A:An optical disc drive, or simply optical drive, is a piece of computer hardware that alters data on optical discs using lasers. Optical drives edit, delete and add content to CDs, DVDs and Blu-ray discs in computers and entertainment electronics. Optical drives are useless without optical discs, which typically are round, lightweight pieces of hardware with small grooves on the shiny side of the disc.
